摘要
用含壳聚糖的PDA培养基培养桃褐腐病菌 (Moniliniafructicola) ,经电镜观察发现 ,当壳聚糖浓度达到 2mg ml时 ,M .fructicola的细胞器减少 ,空腔增多 ;当达到 4mg ml时 ,M .fructicola的细胞受到严重破坏 ,主要是细胞壁破裂 。
Monilinia fructicola, causing soft rot of peach fruit, was cultured on PDA amended with chitosan. The observation on ultrastructure of its hyphal cells showed that chitosan at concentration of 2mg/ml induced decrease of organell and increase of vacuoles in the cell and caused the inner structure confused. It also showed that chitosan at concentration of 4mg/ml caused severe damage of hyphal cell. It caused disruption of cell wall and outbreaking of inner cytoplast or invading of outer media.
